Interesting question. Considering how much other countries have done already at the insistence of the U.S., I'm not really sure where they would draw the line and say, "Enough!"

Recently in Frankfurt, Germany, I complained politely about the special security arrangements in place for flights to the U.S. I noted that all passengers had already passed through the regular German security, so why do it all over again for U.S.-bound flights? Wasn't the first security good enough?

The Lufthansa staff acknowledged the silliness of this and told me that the Germans did it only because the U.S. demanded that it be done. The Germans certainly did not consider the second checkpoint to be reasonable or necessary, but they had to do it, anyway.

When I passed through the second checkpoint, I chanted, "Protect the Empire. We must protect the Empire." The German security personnel found this to be hilarious and laughed openly. One woman working as a screener there took me aside and told me how foolish it is that the U.S. thinks that it has to tell other countries how to conduct security. The Germans really do know how to do these things, you know.
